Another big name vendor, Novell, also had a presence at the show.
Eric Schmidt, CEO and chairman of the Provo, Utah-based company, took part in a panel discussion exploring p-to-p's value in the enterprise. Schmidt said Novell is examining the technology.
"You need a consumer adoption strategy," Schmidt said. "If you have a killer app, with no adoption strategy, you won't get there."
"[P-to-p] is in the early stages where you need to make sure the technology works and [know] what people will use it for," Schmidt added in an interview.
Redmond, Wash.-based Microsoft tested the waters at the show with a booth and by participating in a conference panel discussion.
Dave Stutz, software architect at Microsoft, expressed interest in the value of p-to-p infrastructure as a window on society.
